I am working on a third party Java application for which I need to authenticate its users using Active Directory.
This application is hosted on RHEL 6.5, and uses LDAP to authenticate with Windows Active Directory. The AD server has been set up, and is working fine with an earlier version of the application (which was configured to enable the integration).
For the newer version, the vendor has laid out some steps to modify/configure the application files to connect with the AD server, and which are expected to help us authenticate.
The application has one of its component as CAS, which is currently configured to use database as its authentication handler. When we enter the credentials - username: abcd, password: samplepswd, we are able to login successfully.
As the business requirement is that of authentication with Active Directory using LDAP, we have to modify the CAS properties file. As per instructions from the product vendor, we have changed the following properties to use ldap -
authenticationHandler.type=ldap ldapSSLConfig.enabled=false ldapContextSource.url=ldap://sample.ADserver.example.net:389 ldapContextSource.userDn=abcd ldapContextSource.password=samplepswd ldapAuthenticationHandler.filter=uid=%u ldapAuthenticationHandler.searchBase=OU=DEF,OU=PQR,OU=XYZ,DC=ADserver,DC=example,DC=net
We also need to make changes in the casAuthConfig xml file for the following properties (as anonymous search is not supported): 1. anonymousReadOnly, value is set to false 2. java.naming.security.authentication, value is set to simple
There is provision to use ldap over SSL as well, but currently we are not using that. However, if we do use SSL, additional changes have to be made to the following properties:
ldapSSLConfig.enabled=true ldapSSLConfig.trustStorePath=/home/dir1/subdir1/subdir2/keystorename.keystore ldapSSLConfig.trustStoreType=jceks
These are the only configuration changes done on our (client) side; and in fact the only changes done. Nothing has been added/modified on the server (AD server), except another user, but that has no impact on the existing setup.
After restarting cas to reflect the changes, we encounter the error of bad credentials, although the values entered are correct:

Can anybody please help with this issue? Or possibly point in the right direction? Any help would be greatly appreciated.
